SPECIFICATION forming part of Letters Patent No., 491,871, dated February '7, 1893.

Application filed lune 6, 1892. Serial No. 435,773. (No model.)

.To all 10721/0192, t may concern.:

Be it known that l, Tnoirns L. MGKEEN, a citizen of the United States, anda resident of New York, in the county of New York and State of New York, have invented certain nettr and useful Improvements in Buffers for Railway-Cars; and I do hereby declare that the following is a full, clear, and exact description of the invention, which Will enable others re skilled in the art to which it appert-ains to malte and use the same, reference being had to the accompanying drawings, which form a part of this specification. and in Which- Figure l is a perspective view of the front I5 end of a passenger car provided with my improved buffer, Fig. 2 is a longitudinal sectional view, on a vertical plane, through the car platform, buffer, and its appurtenances; Fig. 3 is a top vieiv of the buffer-plate and zo stem, the movable buffer platform having been removed; Fig. Ll is a top vieivof the outer end of the buttensteni; Fig. 5 a rear view of the butlenplate, with the stein removed; and Fig. 6 is a plan of the movable buiier 2 5 platform with its protecting shield or guard.

Like lettersot reference denote corresponding parts in all the figures.

This invention relates to buffers or bu1npers for railway cars; and it consists of certain 3o improvements upon the buffer for which LettersPatent of the United States No. 302,512, were granted tome on the 22d day July, 1884, which said improvements will be hereinafter more fully described and claimed.

Referring tothe drawings, the letter A designates one of the platforms of a passenger coach equipped with my improved buffer, shown at B. The latter is provided on its rear side, facing the car, with two projecting 4o perforated lugs, C C, between which the plate is recessed, as shown at D, to receive the outer end of the rounded butter-stein E, the plate B being hinged or pivoted upon stem E by a stout pin or pintle, F, inserted through the apertured lugs C C and through a coinciding aperture in the forward end of the butterstem, thus giving to plate B free play upon its stein Within certain limits. The buffon plate B is bored through vertically on opposite sides of its middle hinge, as shown at G G, for the insertion of bolts H Il, by means of which a plate, I, is fastened horizontally to the top of plate B. This plate I extends back of the buffer-plate so as to overlap the car platformA; its rear end being roundedin the arc of a circle having the pivot-bolt or hingepin Ffor its center. The inner rounded end of this horizontal plate I is overlapped and part-ly covered by a guard-plate or horizontal shield, J, fastened upon the stationary plat- 6o form A and extending out over the movable rounded end of the buffer-plate I. That part lof the buffer-stem which projects under-the platform is provided with the usual bufferspring K, impelling the buffer outwardly, so 55v that when the cars are coupled, the buders With their respective platforms I will form a bridge between the platforms of adjacent cars, forming, so to speak, a continuous platform adapted for vestibuled and other cars 7c in the make-up of a train.

Having thus described my invention, I claim and desire to secure by Letters-Patent of the United States:

The combination of the stationary piatform, the spring actuated buffer stem having its outer end rounded and provided With an aperture, the buffer plate having openings near each end, central rearwardly extending lugs with aligned apertures and the curved 8o recess to receive the end of the buffer stem, the pintle passing through the apertures in the said lugs and stem, the movable top plate connected near each end of the butter plate by means of bolts passing through the apertures in said plate, and overlapping the stationary platform and the guard plate or shield fastened upon the car platform and overlapping the inner end of the movable top plate, substantially as described.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two Witnesses.

THOMAS L. MGKEEN. Witnesses:
